How to use decimal hours converter
Switch between a clock duration and the decimal form often used in time records. A quarter hour is 0.25 hours, not 0.15 hours.
Worked example
1:30:00 = 1.5 hours. In the other direction, 2.75 hours = 2:45:00.
What the result means
Decimal output is rounded to six places. Duration output is rounded to milliseconds; a copied displayed value has the same precision.
